The BOSS Great Wall is a tight network of four superclusters. The largest two form a stretched-out wall of galaxies that’s about 1.2 billion light years long!

This is one of only a few supercluster systems ever found.

The Sloan Great Wall, which was discovered in 2003, has a similar size but still not quite as large as the Boss structure, which contains 830 galaxies – twice as many as Sloan and is 170% wider than Sloan.

The BOSS has a mass of 280 million billion suns, (our galaxy, the Milky Way, has over 200 billion stars)It is lurking approximately 5 billion light-years away from the Milky Way, and it is 1.3 billion light-years in diameter.
